is a chute 2O extending downwardly in close proximity tothe shelling disk 8 and the bevel shelling wheel 13. Extending from thechute 18 are parallel. ribs 2l adapted to forma support for arms 22 projecting from opposite sides ofa rag iron 23; the rag iron 2 3 extends downward through an opening 241m the plate 17` and rhas a series oflaterallydisposed teeth25 onits face. which in`` eline downwardly. toward the shelling wheel 8. Mounted on the .plate '17 is a member 26 having oppositely extending projections 27 providedwith slots 28;` similar slots 29 are in the plate 17 andat right angles. rto the slots V28, andl. secureta member `26 to the plate 17 by bolts awhich pass throughthe slots 28 and 29 and are tightened by nuts 31. Preferably integral with themain portion of the rag iron 23, and projecting at right angles. therefrom, is an arm 82 whichrests upon the upper surfaceoit` the member 26. A. bolt 33 extends upward through the inem# ber 26 and through the arm 82 and has thereonl a. coil spring'which` exerts its pressure against the and a washer 35 between the spring 34 anda thumb screw `36 on the upper "and threaded end of the bolt 38.

'Referring to Fig. 4 it willbe noted that theface `of the rag iron28and the shelling disk 8 and the shelling wheel 18 forms an angular opening 13ar through which the corn musttravel; the coiled spring 34 holdsthe rag iron 23` so that thellatter willzyield to accommodate unevenness in the ears of corn, the arms 22 `rocking on the vribs21 of the chute 18,l the pressure of thefspring 341 on the rag iron 23 being regulated byturning 'the thumb screw 36.

extend at an angle laterally of the plate 17 so that adjustment of the member 26 can be `made to move the rag iron 23 toward or from the shellingdislr 8. The slots v28, are at .right angles to the slots 29 so thatthe rag iron can be adjusted toward the shelling ldislr 8 and the shelling wheel 13. i

Different types of corn presentvarying geharaeteristics, one variety will Vbe distinguished by thinness of ears, and another variety will havefears of pronounced ,thickf.ness.these..:differences.require a range ,of

adjustment other than provided by the springe, consequently I have provided the slots in' theplate 17 and the member 26 so that the rag iron 23, when the bolts 30 are loosened, can be adjusted by moving the member 26 and the rag iron 23 connected therewith toward or from the shelling wheels I8 and 13V` or away therefroimto change the size of the openingl.- toaccommodate any type of corn, and after the desired adjustment is made thelniember 26 and the rag iron 23 are secured in thenew position bytightening the nutsl. Usually in this'type of machine the chutes, 2O and the rag iron are connected in such a manner that independent adjustment of the latter cannot beefl'ected, adjustment of the rag iron necessitating'a movement ofV the chute Y 20.' As shown and described in myfdevice the rag iron 23 'and chute `20 are not connected-in-any way thelatter having a fixed position` in relation to the shelling wheels from lwhich itis immovable except by. removing the plate 17 of 'which it preferably forms a part; by constructing the rag iron 23`fa's a separate part and mounting it as shown and described a greater rangeof adjustinent to accommodate varying types of corn is possible and the adjustment is quickly and more readily accomplished;

"The lrange of adjustment permits the rag ironV Qto-*be moved toward either of the shelling wheels 8 and 13 ortowardY both at the same time, andt by utilizing one of the bolts'BO as apivot,. the rag iron 23 can be swung 'about a vertical axis to change its relation tothe shelling disks 8 and 13and tovary the form of the angular opening 13, It will also benoted that .the rag iron 23 can bel readily removed andreplaced Vfor any desired purpose without removing other parts of the mechanism of my device. It will be readily understood7 that,v as usual in this type of machine, motion is given to the shelling wheels S and 13 by rotation of the shaft 1 and the gears connecting it'with the shelling wheels.

I do not limit myself to a rag iron having la liat 'face asV shown, it being evident that Va rag iron having a concave jor convex face may be employed without change in the spirit and efliciency of my invention.

1, In a corn-Sheller, having in combination, a casing, shelling wheels within the casing, slots in the casing, a member on the casing having slots overlying the slots in the casing and atan angle thereto, bolts projecting :through said slots and about which said member is adapted to be adjusted and held inpositiom and a rag iron connected to said member and simultaneously adjustable therej with.

2;' In a corn-sheller, having in combination, casing, shelling/wheels within. the

3, In'a ycorn-sheller, having in combination, a casing, shelling wheels within the casing, a rag iron projecting downwardly within the casing adjacent to the shelling on the member to engage, with the opporV sitelyv extending arms on the rag lironto hold said 4arms on. the supports and Ato inovethe rag iron toward. or from the shelling wheels by the adjustment o-fisaid member.

Ll. ln a corn-sneller, having 'inrcombination, a casing, shelling wheels within the casing, a rag iron projecting downwardly within the casing adjacent to theshelling wheels, ,oppositely extending arms on, the upper part ofthe rag iron resting onfsupports on the casing7 anV adjustable member mounted on the casing, an carin on` the rag iron connected tosaid member, l'arms extending from said member andhaving hooks to engage with the oppositelyextending arms on the ragironto hold them Von their supports and to move the rag iron toward or from the shelling Wheels by the adjustment of said, member. i

5.111 a corn-Sheller, having inicombination," a casing,v shelling wheels, within the Y casing, a rag iron' projecting `downwardly within the casing.' adjacent to the shelling wheels, oppositelyextending arms on the rag iron restingA on supports onv the casing, an `adjustable. membermounted on the casing, an arm on' the rag iron Y'connected to said member by bolt thereon adapted to project throughan openingin said arm, a nut on the free'end of the, bolt,.a coil spring on the bolt between the nut .and said arm, means to adjust said member; fandmeans connecting said member and 'the oppositely extending arms on thef rag iron to move Athe latter towardor froml the shellingwheels bythe adjustment of said member. l 6. In a corn-Sheller, having in combination, shelling wheels',` aV chuterigidly supportedV in4 fixed ,relation tothe shelling wheels and through which .corn ispassed to be shelled, ya rag iron forming withY the shelling wheels an angular passage toA reeive corn from the chute, and means to adjust the vrag iron laboutfa vertical axis forward ofthe chutefto varyits .angular relation to the shelling wheels'.

7-:5In a cornfsheller, having'in combinaifioi j tion, shelling whee1s,a chute rigidly supported in fixed relation to the shelling wheels and through which corn is passed to be shelled, a rag iron forming with the shelling wheels an angular passage to receive corn from the chute, and .means to adjust the rag iron about a vertical axis forward of the chute toward one of the shelling wheels to vary its angular relation to both of said wheels.

8. In a corn-Sheller, having in combination, a casing, shelling wheels within the casing, a chute within the casing adjacent the shelling wheels and through which corn is passed to be shelled, a rag iron forming with the shelling wheels an angular passage to receive corn from the chute, and means to adjust the rag iron only about a vertical axis forward of the chute toward or from the shelling wheels to vary its angular relation to the latter.
